Impossible to boot from [new] cd/dvd drive - pavilion dv6700

Specs: Windows 7
Hey guys,
as from the title, my cd drive stopped working on my laptop [hp dv6817el / win7 x64]. The led, eject button are working and the drive spins when a new cd is inserted although nothing happens.

In the windows Event viewer I have a
"The following boot-start or system-start driver(s) failed to load:
cdrom" error on startup.

Anyway, if I try to reboot using the optical drive first in the booting order, with a bootable cd inserted indeed, it spins the cd but nothing happens and it continues loading the OS from the local hd. The drive is a HP TS-L632.

I have been searching on the web but I couldn't find any fix. I thought the drive could be broken (since it is ignored in the boot sequence) so I bought a new one. Unfortunately, the same behaviour....

Could you suggest anything on this issue? If the drive is ignored in the boot sequence then it doesn't depend on windows, therefore could it be the motherboard bios [on which I set the options to defauts without any success]?

Any help is greatly appreciated!

I was told to do this and this
go to safe mode with command prompt and do the first one first,,,,,,,and I also do this one. Scf/scannow this one worked for me,,,

So a stop 0xf4 is either a bad hard drive, corrupted windows, or viruses.
If you can get into safe mode command prompt. you should be able to run
chkdsk C: / This one is what everyone is telling me to do

Go into the Command prompt and type:
hit enter,
hit enter,
If you see folder names like "windows" and "users" then your on the right partition, if not try D: after you find your windows partition type
chkdsk C: /r
chkdsk D: /r
after that finishes
bootrec /fixmbr
bootrec /fixboot
sfc /scannow /offbootdir=c:\ /offwindir=c:\windows
sfc /scannow /offbootdir=d:\ /offwindir=d:\windows
when that's done

With many BIOS' today you need to 'hit any key to boot from CD/DVD drive'. This is typically shown briefly along the bottom of the screen during boot up, but the system mfg. may have been able to turn this notice off or block it from view. Try tapping any normal key repeatedly during boot up with the bootable disk in the drive and see if that helps.

You have to be a little bit crazy to keep you from going insane.

I had the exact same issue with about 6 or 7 DV6000 models. It has to do with the nVidia chip failing.

Sorry for the bad news
